Abstract

Fluorescent probes for hydrogen sulfide have received considerable attention because of the biological significance of H2S recognized recently. However, near-infrared fluorescent probes for H2S are still rare. In this work, a new near-infrared fluorescent probe for H2S was developed based on the reduction reaction of azide with H2S to amine based on the fluorophore of dicyanomethylene-4H-chromene because of its long excitation and ...
